• Implement simple RTL preprocessor in PdfSharp.Events.RenderEvents that detects Hebrew-script characters (U+0590..U+05FF and U+FB1D..U+FB4F) and reverses RTL runs before PrepareTextEvent handlers are invoked. • Keep heuristic limited to Hebrew-script languages (Hebrew, Yiddish, Judeo‑Ladino) to avoid complex shaping issues. • Add unit tests ReverseRtlTests to verify mixed LTR/RTL run reordering. • Remove broader RTL detection that included shaping‑required scripts. Files changed: • src/foundation/src/PDFsharp/src/PdfSharp/Events/RenderEvents.cs • src/foundation/src/PDFsharp/tests/PdfSharp.Tests/Drawing/text/ReverseRtlTests.cs
